ELECTRIC BODY-BATTERY.

SPECIFICATION forming part of Letters Patent No. 420,936, dated February11, 1890.

Application filed June 26, 1889. Serial No. 315,644. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER S. HALL, a citizen of the United States, anda resident of Marion, in the county of Linn and State of Iowa, haveinvented certain new and useful Improvements in Electric Body-Batteries;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to 'make and use the same.

My invention has relation to electric bodybatteries for the treatment ofvarious forms of disease by the local application of an electric currentto the affected part or parts; and it consists in the construction andnovel combination of parts,-as will be hereinafter fully described andclaimed.

In the accompanying drawings, forming part of this specification, inwhich like letters of reference indicate corresponding parts, Figure 1is a view in perspective of an electric body-battery embodying theimprovements of my invention. Fig. 2 is a view of the electric chainremoved from the pocket in which it is usually worn, showing also thepositive and negative flexible wrapped wires and the positive andnegative buttons at the ends thereof; and Figs. 3 and 4 show reverseface views of the positive and negative buttons at the ends of theirrespective wires and the safety-pins forsecuring said buttons to theunder-garment of the wearer.

Referring by letter to the accompanying drawings, A designates acentrally-longitudinal divided cloth or flannel pocket, which is linedwith water-proof material B-such as rubber or oil-cloth-to prevent thechargingacid from coming in contact with the clothing or person of thewearer, the battery and its covering being preferably worn in thehip-pocket of the male patient or in the bustle of the female patient,such location being preferable for the sake of convenience. The

pocket A is open at both ends, the end 0 being provided with a flapD,having a buttonhole E, which is designed to receive the closing-buttonF on one face of the pocket A.

The battery comprises achain of connected alternating copper and zincdisks II and I, having interposed felt disks K, united by threads, thecopper disks and zinc disks alternating, as shown-that is to say, thecopper and zinc disks are alternately above and below. The completeddisks are connected by hinged links L, which engage eyes M on one sideof each link. The battery in this instance is immersed or dipped invinegar or diluted acid in order to energize it, and is then placed inits water-proof pocket. The positive and negative wires 1 2 are providedat their attaching ends with concavo-convex buttons X, of block-tin,provided with safetypins Y for attaching them to the clothing of thewearer, so that the convex portions of the buttons may come in contactwith that portion of the person of the wearer to be treated for disease.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A cover for body-batteries, composed of flannel or like materialformed into a rectangular shape, having a central longitudinal seamdividing it into two open-ended compartments, and also provided at itsupper end with a flap having a suitable button-hole for engaging abutton on the face of the cover, substantially as set forth.

2. A cover composed of flannel or like material formed into arectangular shape, having a central longitudinal seam dividing it intotwo open-ended compartments, said cover being lined with water-proofmaterial, and also provided at its upper end with a flap having asuitable button-hole for engaging a button on the face of the cover, incombina tion with a galvanic belt consisting of a chain of alternatingcopper and zinc disks, having interposed felt disks, suitably connectedby means of eyes and links, positive and nega-. tive wires connected tothe ends of said chain, and electrodes secured to said positive andnegative wires, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereuntoaflixed my signature in presence of two witnesses.

OLIVER S. HALL.
